Protein Family Models

This domain is found in bacterial flagellar M-ring (FliF) proteins together with the YscJ/FliF domain (Pfam:PF01514). (from Pfam)

This family includes proteins that are related to the YscJ lipoprotein, and the amino terminus of FliF, the flageller M-ring protein. The members of the YscJ family are thought to be involved in secretion of several proteins. The FliF protein ring is thought to be part of the export apparatus for flageller proteins, based on the similarity to YscJ proteins [2]. [1]. 1332940. MxiJ, a lipoprotein involved in secretion of Shigella Ipa invasins, is homologous to YscJ, a secretion factor of the Yersinia Yop proteins. Allaoui A, Sansonetti PJ, Parsot C;. J Bacteriol 1992;174:7661-7669. [2]. 10049798. A structural feature in the central channel of the bacterial flagellar FliF ring complex is implicated in type III protein export.

flagellar M-ring protein FliF is part of the M-ring, which is integral to the inner membrane of the cell and may be actively involved in energy transduction

Component of the M (cytoplasmic associated) ring, one of four rings (L,P,S,M) which make up the flagellar hook-basal body which is a major portion of the flagellar organelle. Although the basic structure of the flagella appears to be similar for all bacteria, additional rings and structures surrounding the basal body have been observed for some bacteria (eg Vibrio cholerae and Treponema pallidum).
